Method of generating brush touch effect using touch pad

The invention relates to a method using a touch pad (Touch Pad) that the illusion of painting write or with a brush. The present invention includes the steps of detecting a movement of the touch pad (Touch Pad) touch the object (Object Touch), such as a user's finger or pen is in contact with; Reconstruct the contact area between the touch object and the touch pad from the detection signal into an oval, and seek an acceleration according to movement of the touch object, to generate the coordinates through a spline method (Spline Method) to obtain the curve relative to the motion of the touch object step; Based on the data on the deformable object (Object Deformable) obtained through the learning process in the off-line step of modeling the object, the touch sense signal in real time; A step of based on the analysis determine the thickness, shape, and density of the brush according to the touch object movement path, and creates the display image brush strokes corresponding to the determined thickness, shape, and density; And characterized by comprising comprises a.
